POWER APPARATUS.

Application filed August 24;, 1921. Serial No. 495,012.

To all whom it may concern: 1

Be it known that I, JAMES Azvnnnsozv, a citizen of the United States, and resident of Nicolaus, county of Sutter, and State of California, have invented a new and useful Power Apparatus, of which the following is a specification.

The present invention relates to improvements in pumps and is a combination of a siphon and a centrifugal pump. Its object is to provide a pump that can normally be used as a siphon but can be very easily changed into a centrifugal pump when the level of the water to be drawn on gets so low that the siphon would not work. My pump is intended mainly for irrigation purposes. and in perfecting it I had in View land that is separated from a river by a levee and where the water at certain times of the year rises above the level of the land so that it can be turned'on the land by an application of the principles of gravity through the medium of a siphon, but where at other times the water level is below the land level so that power is required to pump it on the land. Under these conditions the farmer very often does not feel justified in going to the expense of installing an extra pumping plant in addition to his siphon, but would probably find it convenient to use my combination siphon and pump.

lVhile. my invention has thus been developed in view of certain conditions I do not wish to be understood as confining myself thereby, but I wish to get protection on the principles involved as defined in the claim without being limited by the particular embodiment of the same shown in the drawings and the description.

In the accompanying drawing Figure 1 shows a plan view of my combined siphon and centrifugal pump, Figure 2 a side view of the same, Figure 3 a side view of the same, partly in section, with certain parts shown turned on the axis of the body of the pump, Figure l an end view of a propeller used in my pump, Figure 5 a sectional view through the same along line 55 of Figure l, Figure 6 a detail end View of a standard supporting the pump and Figure 7 a crosssection through one of the blades of the propeller along line 77 of Figure 4.

' Re e ng t h draw ngs in detai it bolts (8) peneterating holes (9) in register-- ing flanges'(l1) of the twohalves.

This ring embraces the body ofmy pump (12) and is provided with an annular-recess (14c) PATENT o cs.

adapted to receive an annular projection (16) on the outside of the pump gsothatthe pump can be, rotatably adjusted in the ring but does not slide in the same. i

The pump (12) forms a part of a siphon, which latter comprises a suction pipe (18), a

horizontal pipe adapted to carry-the water through a desired distance, and the discharge pipe (21). My pump forms a portion of the horizontal pipe and consists of a tubular body (22) having a diameter about i twice the length of the siphon diameter. To

connect it into the pipe, a portion of the horizontal plpe is removed and' the remaining portions are axially d1sal1ned,'so that one of Said Portions (23)'1Y1%W axially aline-d With, epump, while the other portion (24) may be connected to the body of the pump by a slanting pipe (25) entering the side of the body. This latter is conically reduced atits front end to be connected to pipe (23) by means of the two flanges (26) and (27-).

The rear end of this pump (12) may be closed by an ordinary plate, not shown in the drawing, secured to the flange (28) of the body, and in that case the pump is in active and the whole apparatus used as a siphon only.

To use the pump I take off the ordinary plate and use in its place the plate (31) shown in the drawing. It is secured to the flange (28) by means of bolts 29') and has a nozzle shaped projection extending into the inside of the pump adapted to serve as a beari g for the shaft which extends through said projection and car ries, at its end, the propeller (33). The latter consists of the hub (34), a plurality of blades (36) and a rim (87,) which latter comes ra r close to the Per p ry f e loo ' tubular body of the pump and bears against I The propeller blades are shapedas shown in Figure 7, that is the suction side has a steeper pitch than the discharge-side, whereby strong suction and high pressure are obtained.

is provided in the bearing for the shaft, and where-the shaft 632 enters theface'p'late,

wpacking (4-2) is introduced in an annular recess (43) andipressed inwardly by the [gland L4) actuated by a'cap (d6) secured to'the face;-p1ate"by means of bolts (47). 1n this JDEHIDGIILH absolutely water and air tight fit is obtained around the shaft '32). The far end of the shaft (323 restsiii the bearing (51) supported on the standard (512). This bearing is shown in sec- .tion in Figured and comprises a bearing container i (55) :to which a cap (53) is (screwed. IAbolt (5e),-hayingahead (56) outside the cap and a disc (52)securedto its in1ier,end,-extends through the cap :and isv ad-atpted to be-adjusted i-n..the same by being screwed backward I and "forward; The discser ves as the outer race of a thrust ball bearing, the ,inneTFTfdC-G being formed by a sleeve secured on the reduced end of the shaft (32). Aabushing (F59) separates the shaft fromithebearing container which latter is provided with inner annular grooves (61;) for-the receptionrand distribution of oil. The pump iiisflrun by any power available, which may transmit IDO- tion' to .the shaft by. means of the pulley (62). :To prin'ie'the pump I use an ordinary hand pump ('63) .assho-w'n in Figure- 2, by ,means of which .the air may berpumped out of the body .of the pump, after the discharge pipe has bGG11--21,lr tightly closed.

F -;A removable-plate (64:) allows thepump I to' be cleaned by han-d ,in case the passages of weeds, etc.

The operation of the mechanism will be readily understood. TWhen the level of the water to be pumped is higher thanthe land, the siphonalone is used. hen the water recedes during the dryseason, so that its level falls below the level of'tlie land, the

pumping mechanism can be easilyinstalled: and the water pumped on the land. My Near the propeller a brass-bushing (4:1) I

mechanism can atthesa ne time readily be used to pump in the opposite direction by merely reversing the rotation of thehsliaft.

Thisuma-y become of extreme importance in" rcase-iof heavy rainfalls or floods, where it v is desired to pump the water from the land operator toveasily turn the discharge pipe upwardiso :astto lead the water into a tank orthe hke; as'shown in :Figure 3.

Proper valves ('65 and (66)are provided in thesuction and discharge pipes to regu- -late the-amount of liquid to be handledby the rpump. it
